1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Interleukin-12 (IL-12) holds significant potential in cancer therapy; however, its clinical applicability is hindered by dose-limiting toxicity. Delivery of the IL-12 gene directly to tumours for constitutive IL-12 expression is a possible strategy to enhance its effectiveness while minimizing systemic toxicity. In this study, we investigate the potential of red blood cell-derived extracellular vesicles (RBCEVs) as a carrier for Il-12 plasmid delivery. We demonstrate that RBCEVs can be loaded with minicircle plasmid encoding IL-12 and delivered to MB49 bladder cancer cells for IL-12 expression. The expression of transgenes from minicircles was significantly higher than from the parental plasmids. RBCEV-mediated IL-12 expression stimulated immune responses in mouse splenocytes. Intratumoral delivery of Il-12 plasmid-loaded RBCEVs suppressed bladder cancer tumour growth, stimulated immune responses and promoted immune cell infiltration. In conclusion, our study demonstrates the promising potential of RBCEVs as an effective, safe and redosable nucleic acid drug delivery platform for IL-12.
